Gloomy forecast for the Aletsch Glacier
Gloomy forecast for the Aletsch Glacier
The largest glacier in the Alps is visibly suffering the effects of global warming. ETH researchers have now calculated how much of the Aletsch Glacier will still be visible by the end of the century. In the worst-case scenario, a couple patches of ice will be all that's left. Every year, it attracts thousands of visitors from around the world: as the largest ice flow in the Alps, the Great Aletsch Glacier is a major tourism draw in the Swiss region of Upper Valais, second only to the Matterhorn.

Brain: How to optimize decision making?
Brain: How to optimize decision making?
UNIGE researchers demonstrate that our brains do not make decisions based on their inherent value but for what they offer above and beyond other possible propositions. Our brains are constantly faced with different choices: Should I have a chocolate éclair or macaroon? Should I take the bus or go by car? What should I wear: a woollen sweater or one made of cashmere? When the difference in quality between two choices is great, the choice is made very quickly.

Global Sustainable Development Report calls for urgent, coordinated action
Global Sustainable Development Report calls for urgent, coordinated action
A world without poverty, in which everyone's well-being is ensured: achieving this goal by 2030 is still possible, but only if the relationship between people and nature is fundamentally changed and social inequalities are reduced. That is the conclusion of the 2019 UN Global Sustainable Development Report, drafted by an independent group of scientists co-chaired by Peter Messerli, University of Bern, and Endah Murniningtyas.

Chromatin looping: CTCF versus ADNP
Chromatin looping: CTCF versus ADNP
The organization of chromatin in the three-dimensional space is complex and requires the help of many proteins, including CTFC. Researchers from the group of Marc Bühler have identified a new player in the process: the transcription factor ADNP. In a recent study, they show that ADNP competes with CTFC, acting as a local modulator of chromatin looping.

Treating more wastewater with less energy
Treating more wastewater with less energy
More and more people are moving to cities and agglomerations in Switzerland, which is putting extreme pressure on some wastewater treatment plants: Because they are having to treat greater volumes of wastewater, their energy consumption is skyrocketing. And some WTPs are close to reaching capacity. Together with various project partners from industry, Eawag has now been testing out a new kind of technology for the past six months at the Sihltal WTP.

Building Blocks of Bird Babble Identified
Building Blocks of Bird Babble Identified
A new study by an international team headed by the University of Zurich sheds light on whether animal vocalizations, like human words, are constructed from smaller building blocks. By analyzing calls of the Australian chestnut-crowned babbler, the researchers have for the first time identified the meaning-generating building blocks of a non-human communication system.

Feeling legs again improves amputees’ health
Two volunteers are the first above-knee amputees in the world to feel their prosthetic foot and knee in real time. Their bionic prosthesis, which was developed by an international team of researchers, features sensors that connect to residual nerves in the thigh. The resulting neurofeedback greatly reduces physical and mental strain for users of the prosthesis.

Making and controlling crystals of light
Making and controlling crystals of light
EPFL scientists have shown how light inside optical on-chip microresonators can be crystallized in a form of periodic pulse trains that can boost the performance of optical communication links or endow ultrafast LiDAR with sub-micron precision. Optical microresonators convert laser light into ultrashort pulses travelling around the resonator's circumference.

Audition: How our brain filters sounds
Audition: How our brain filters sounds
Researchers at UNIGE have demonstrated that the brain adjusts the attention it gives to identical sounds as soon as they are perceived in the brainstem, a capacity that is lacking in schizophrenics. Our sound environment is extremely dense, which is why the brain has to adapt and implement filtering mechanisms that allow it to hold its attention on the most important elements and save energy.

Resistance can spread even without the use of antibiotics
Resistance can spread even without the use of antibiotics
Antibiotic resistance does not spread only where and when antibiotics are used in large quantities, ETH researchers conclude from laboratory experiments. Reducing antibiotic use alone is therefore not sufficient to curtail resistance, and should be done in conjunction with measures to prevent infection with resistant germs.

Natural ways of cooling cities
Natural ways of cooling cities
ETH scientists have been researching the effect of precipitation and population size on rising temperatures in cities compared with the surrounding countryside. They have found that more green spaces can help to lower temperatures in urban zones - but not everywhere. Urban heat islands are a phenomenon where the temperature in a city is noticeably higher than in the surrounding rural area.
